STRIP BLOCKING OR WINDING MACHINE.

Specification of Letters Patent.

Patented Oct. 22, 1918.

Application filed September 4, 1917. Serial No. 189,486. I

To all whom it may concern:

Be it known that I, ABEL KENWOR HY, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Strip Blocking or WVindin Machines, of which the following is a specification, reference being had therein to the accompanying drawm s.

My invention consists in new and use 111 improvements in machines or appliances for winding or coiling sheet material, and has for its object, among other things, to produce an efficient and simple device, which can be readily attached to or associated with a strip delivering machine.

The invention may be utilized with advantage on machines for manufacturing or handling sheet metal, card board, oil cloth, wire mesh, floor covering or other material put up in the form of coils or rolls.

The purpose of a device of the class to which the present invention belongs is to mechanically hold the end of the strip of sheet material to be wound against the block and to guide and continually hold the material in close relation around the block or the initial turn or turns thereof, thus obvlating the necessity of the operator holding the strip by hand, at great risk of injury to himself and loss of time.

To the above recited, and other ends, theinvention consists in the strip or sheet material blocker or winding appliance, hereinafter described, and having certain details of construction and combinations of parts, as will be hereinafter set forth and more particularly pointed out in the claims.

Referring to the drawings, in which like numerals of reference designate like parts in the several figures: I

Figure 1 is an elevation of the device, shown in complete form, and having its individual supporting bed and winding drum or block;

Fig. 2 is a plan View of the same; and

Fig. 3 is another elevation looking toward the rlght of Fig. 1. a

In the practice of my invention I am enabled to utilize as a bed or base therefor the frame of the machine to which the device is to be applied, or if the winding apparatus is to be supplied as a self-contained appl ance it would be provided with its individual winding block or drum and supporting bed therefor, together with the other novel parts constituting part of the invention herein.

According to the application of the invent1on as illustrated, the bed or base for the blocking or winding device consists of the frame 1, which supports the block or drum 2 mounted on shaft 3 supported in suitable bearmgs and rotated by any ordinary means, or the drum may be turned manually if desired.

My improved device is secured to the frame 1 by means of lugs or brackets 4 carried by the frame or by the appliance itself. Additional means for supporting said device consists of the bracket 5 secured by bolts 6 to the frame 1. Substantially parallel bars 7 are rigidly held by said lugs 4 and bracket 5 and the sleeves or blocks 9 and 10 of the deviceare slidably mounted respectively on said bars 7 and 8. The sleeves 9 and 10 are united by a frame 11 and slide as a unit upon their respective bars 7 and 8.

The sleeve or block 9 pivotally supports an arm 12 on shaft 13 which is provided with bearings carried by said sleeve 9. A segment 14 is. mounted on the same shaft and is adjustably connected to the arm 12 by means of the bolt 15 that passes through theslot 16. An idler pulley 17 is rotatably mounted upon shaft 13 and similar rollers 18 and 19 rotate on their respective studs 20 carried by the arm 12. This arm turns on its pivotal support under action of the manually operated lever 21 through a system of connecting links 22 and 23, which links when past the center operate as a locking device to maintain the arm 12 in the lowered position. A link 24 pivotally secures the lever 21 to the bracket 25 carried by the sleeve or block 9. The system of connecting links referred to includes a bell crank intermediate lever 39 which is pivotally connected to bracket 26 carried by the sleeve 10.

The arm or member 27 consists of a air of rods carrying at the ends a forked hea serving as a bearing for the idler pulley 28. Coil springs 10 surround these rods between the collars 29 and the pivotal block 30. The tension of these springs is varied by means of the nuts 31. The angular position of said rod or arm is adjusted by means of the set screw 32, which can be manipulated to vary the relative position between the projection 33 forming part of the block 30 and the lug 34 carried by the sleeve or block 10. A corresponding projection 11 having adjusting devices is provided to limit the drop of the arm 27.,

Idler rollers 17, l8, l9 and 28 operate as guiding rollers for a belt 35 which passes partially around them and the drum or block 2 when the appliance is in its operative position, the idler 28 serving as a tension device, varying the frictional contact of the belt with the drum 2.

The entire operative parts of the appliance are moved on the bars 7 and 8 into and out of their winding positions and a spring 36 is provided to ofier a cushion between the sllding member 9 and the point of its abutment with the base 1, and to minimize friction, anti-friction devices 42 are interposed between the sliding member 9 and the bar 7. The spring 36 also exerts a pressure upon the appliance that increases the tension of the belt 35 against the drum 2.

In the operation of my improved device the winding drum 2 is rotated by any suitable means, for example, the belt 37, and the strip 38 is fed from a delivery machine (not shown). When in use, the operative parts of the appliance are in the full line positions shown in Fig. l of the drawings. hen the material is coiled around the drum sufficiently to liold itself, the lever 21 is operated, and through the connecting links and segment 14, the arm 12 is lifted so that the belt and roller will be in the dotted line position shown. Finally when the diameter of the drum increases, owing to the winding of material thereon, the appliance is pushed bodily along bars until the belt and rollers are in the broken line position shown, or if desired, the parts can be moved beyond that point, up to the bracket 5.

There are minor changes and alterations that can be made within my invention, aside from those herein suggested, and I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of the appended claims.
